Black,'Brooklyn, N. Y. Application March 21, 1946', SerialfNo..-65,,6,010

This invention relates to bedsheets and blanks for manufacturing them.

. ,An object ofthe. invention is'to .providea bed sheet with .meansto .retain'it in stretched-position about a. mattress, preventing slippageand displacement of the sheetwith relation tov the mattress.

A further objectis t0..prov ide aself-adjusting and-"stretching bed sheet-thatcan be placed easily a uta mattress, covering. itaupp'er face. its. sides an er phe l. por ons r s unde side- Another object is toprovide; a'bed sheet with soc s. qcnv iently d sposed t e n. so h contents of the pockets will be readily accessible.

Still another object is to -providea sturdy bed sheet with reenforced corners of specialconi l-mien.

epqa r. m n 1. rovide-blank mwl i such sheets can be made readily in large numbers and at low cost.

These and other objects are accomplished in one form of the invention by providing a bed sheet formed with a rectangular central portion, side portions laterally enclosing the central portion, two pockets opposingly disposed on the longer flaps near one end, a fold extending along the free edge of each side portion, an elastic element in the folds drawing them together, and four reenforced seams defining the corners For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure- Fig. 1 is a perspective view looking down on aself-stretching and adjusting bed sheet in position on a mattress.

Fig. 2 is a perspective view of the underside of the bed sheet shown in Fig. 1.

Fig. 3 is a sectional view through the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary perspective detail view of a corner of the mattress with the sheet positioned thereon, the edges of the sheet being untucked.

Fig. 5 is a plan view of a blank from which a sheet similar to the sheet shown in Figs. 1 to 4 inclusive can be made.

Fig. 6 is a perspective view of a variation of the invention in position on a mattress.

Fig. 7 is a fragmentary perspective detail view of the corner of the mattress with a sheet similar 2 to theone shown in Fig. 6. positioned thereon, the edges of the sheet being untucked.

Fig. 8 is a perspective View of a corner reenforcing element of the sheet shown in Figs. 6 and'l.

Fig. 9 is a fragmentary sectional view along the linejS- Q of Fig. 6.

Fig. 10 is a plan view showing a step in the manufacture of the sheets shown in'Figs. 6 and 7.

In the drawings and in the "specification, in which likereference numbers designate similar parts, a one-piece self-stretching and adjusting bed. sheet [.5 shown in Figs. 1 to 4 inclusive,.i s positioned on a mattress It, with a rectangular top portion l1v overlaying the top of the mattress, two long sides l8 and two short sides Ilihugging the sides and endsof the mattress, and a bottom portion 2;} having alargerectangular opening 2| underlying a portion of the underside of the mattress adjacent its periphery. An elastic element 22 extends about the opening 2 I, resting and held within an edge fold 23 about the mouth of the opening, and tending to reduce its size. Stitches 24 extend from each corner 25 of the opening 2| to each corner 26 of the top portion ll, defining the junctions of the sides l8 and [9.

The bed sheet I5 can be made from a blank 2! such as is shown in Fig. 5. This blank, which is made of the usual sheeting material, is in the shape of a rectangle with square cut out corner portions, leaving two long opposite side flaps 28 and two shorter opposite end naps 2B, the naps 23 and 29 each having a fold 36 along its Iree longitudinal edge. Ad acent nap edges 3| and 32 of the flaps 2B and 29 respectively are joined by stitches and an elastic element positioned within the folds, forming the bed sheet is with the stitches 24 and the elastic element 22.

A modified bed sheet 33, shown in Figs. 6 and 7 can be made from a blank 34 like the one shown in Fig. 10. In this variation of the invention, outside edges 35 of an L-shaped reenforcement member 36 (see Fig. 8) are secured by stitches 3'! about the cut out corners of the blank 34 which is provided with two pockets 38 disposed on opposite sides thereof near one end, each pocket having an opening 39 facing toward the center of the sheet. In all other respects, the blank 34 is similar to the blank 2'! heretofore described. The procedure to form the bed sheet 33 follows the same steps as those described to make the bed sheet I5, stitches 40 securing the inside edges of the reenforcement member to the cut out corner edges 4| and 42 of the long flaps 43 and transverse flaps 44 respectively to form reenforced corners 45 on the bed sheet 33.

In the position of the sheet 33 on the mattress, the pockets 38 are positioned on opposite sides of the mattress l6 near one of its ends with the mouths 39 of the pockets uppermost and except for the reenforcement members and the pockets, the sheet 33 is similar in all other respects to the sheet 15.

The bed sheets 15 and 33 can be made in various sizes to fit over conventional mattresses. When positioned about a suitable mattress, the elastic element retains the sheet neatly in stretched position preventing slippage and displacement. 7

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reversed to all changes and modifications coming within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

A bed sheet for covering a mattress, comprising a piece of cloth materialof a size to have a center portion extend across the top of the mattress and side portions projecting beyond the periphery of the mattress, the side portions of the piece of cloth material having square cutouts cut in the corners of the sheet with the inner corners of the cutouts located at the corners of the mattress, stitches securing together the adjacent ends of the side portions of said piece of cloth material with said side portions extended at right angles to each other and at right angles to said center portion so that said side portions 4 can be extended downward along the sides and ends of the mattress and then inward partially along the bottom face of the mattress with the line of stitches extended downward at the corners of the mattress and radially inward at the bottom of the mattress, said side portions having their free edges folded inward forming guideways, a continuous elastic band extended through said guideways for drawing said side REFERENCES CITED The following references are of record in the file of this patent:
